Ecomusée de la région de Fourmies-Trélon, Regional ecomuseum in Fourmies, France

The ecomuseum in Fourmies consists of two sites dedicated to textile and glass production, documenting industrial heritage through preserved machinery and objects. Each location shows different craft techniques that were central to the local economy across generations.

The écomusée de l'Avesnois was founded on 13 June 1980, when its first general assembly met at the Fourmies site, housed in the Prouvost-Masurel worsted spinning mill that ran from 1874 to 1978 at a spot called "En dessous des moulins". The Sains-du-Nord and Trélon sites opened in 1983, and in 1990 the ecomuseum received the European Museum of the Year Award. In 2019 it became a public establishment for cultural cooperation.

The Fourmies site occupies a former Prouvost-Masurel wool-combing mill that ran from 1874 to 1978 at a spot called "En dessous des moulins". Its 2,500 m² hold a steam engine and a large working machine park, with displays on textile production from raw fleece to finished cloth and on working-class daily life at the end of the 19th century.

The two sites lie in different towns: the textile museum in Fourmies, the glass workshop in Trélon, about 15 km apart, so a car is useful to see both. The Fourmies site covers 2,500 m² in the former Prouvost-Masurel spinning mill, so allow time for the machine halls. The Trélon glassworks dates from 1823.

At the glass workshop location in Trélon, visitors can watch craftspeople blowing glass and creating pieces using traditional methods. This living craft practice allows visitors to experience how this ancient art form is still practiced today.
